UPDATED: Vick warms up but doesn't practice

Michael Vick, three days removed from a concussion, participated in the Eagles' walkthrough Wednesday morning.

Head coach Andy Reid was optimistic Vick might be able to take snaps at practice in the afternoon but that didn't happen.

"We'll just see how things go," Reid said. "If he can't go the other guys will take the reps.

"I'm fortunate to have three guys I can go to."

The other guys are quarterbacks Mike Kafka and Vince Young.

Kafka finished the Sunday night loss to the Falcons as VY was scratched for the second straight game due to a strained hamstring,

Vick, on the other hand, is being monitored almost minute by minute.

"I'll tell you right now, he's right in the middle of this process and everything is progressing," trainer Rick Burkholder said, adding the MRI Vick underwent Tuesday was negative. "He's in a very close range to being right back to where (his baseline was) in the summer."

Under the NFL's concussion guidelines players take a baseline test upon reporting to training camp.

Vick also took an impact test Tuesday. Burkholder feels the veteran would need one more slightly better such test to continue making progress.
